I think Power of the Dog (2021) was a great film partially ruined by the miscasting of Benedict Cumberbatch. Now I agree that he is a good actor but he doesn't have the facial features that make him fit for the role of a tough, cattle-ranching, American cowboy. I wouldn't necessarily ask for a Sam Elliott or a John Wayne type that would just turn the movie into a caricature of itself and I am guessing director Jane Campion wanted avoid that partly by casting him for the role but I think it was too far out of the expectations which made him stick out in a bad way. I remember thinking to myself while watching, "this is a great story but I keep losing my immersion every time Cumberbatch appears on the screen."
I still to this day don't get the casting of Edward Norton for the Hulk.
